I am attempting to use the nodeCheck functionality within an OnChecked event.  I need to be able to uncheck the passed item under certain circumstances.  I am using the following code:

function OnChecked(e) {
    //logic here to determine if uncheck is needed....

    $('#TreeView').data('tTreeView').nodeCheck(e.item, false);
}

Nothing seems to happen - the item remains checked.  The e.item is returning properly and I can get the Text and Values, as well as the current checked status.

My current setup
  • ASP.NET MVC version :  2
  • OS : Windows 7
  • exact browser version : Firefox 3.6.12 / IE 8.0.7600.16385
  • exact version of the Telerik product :  Extension for ASP.NET MVC Q3 2010
  • preferred programming language (VB.NET or C#)  : C#

  • Thanks,
    Emily

    Hi Emily,

    Instead of trying to un-check the item you can cancel the onChecked event:

    function OnChecked(e) {
        //logic here to determine if uncheck is needed....
        e.preventDefault();
    }

    I hope this helps.

    Thanks - that works great for the uncheck option. 

    If I wanted to check something, the nodeCheck method seems like the best way to go, if it works.  Is there another option?

    Hello Emily,

    The current node will get checked if you don't cancel the onChecked event. The nodeCheck method can be used for checking/un-checking other nodes:

    var treeview = $("#TreeView").data("tTreeView");
    var item = $("li:first", treeview.element)[0]; //DOM element
    treeview.nodeCheck(item, true);
